Season four of The Traitors is already shaping up to be a wild ride. It’s clear the producers came into The Traitors 2026 with one goal: chaos. This time around, it’s not just the Faithfuls left in the dark — everyone is scrambling to uncover secrets in the castle.
Claudia Winkleman wasted no time in episode one, shocking viewers with the introduction of a Secret Traitor, who was later dramatically revealed. But it’s becoming increasingly clear that this twist is just the beginning of this season of the BBC series.
From suspicious coincidences to emotional reunions, it seems old friends, partners, and even family members are finding themselves face-to-face under the most intense circumstances imaginable.
So, who knows who, and what does it mean for the game? Let’s break down all the relationships on The Traitors season four.
Expect the unexpected this season, including a war between Traitors.
What is the Family Theory?
Eagle-eyed fans are convinced that everyone on The Traitors is secretly connected to another contestant. The theory first gained traction when Judy and Roxy revealed they are mother and daughter — a twist that was all the more heartbreaking given Judy had just been wrongly banished from the game.
Fuel was added to the fire thanks to the literal family tree–style painting hanging in the castle foyer, which appears to link contestants together across different branches. Subtle? Absolutely not.
Some viewers believe the twist goes even further, with each contestant having both a primary connection and a looser secondary link. This theory gained momentum when Ross entered the castle with his girlfriend, only to later come face to face with an old friend, Netty.
Whether this is an elaborate production masterstroke or a series of wild coincidences remains to be seen. But if the pattern holds, it seems we’ll only uncover these hidden relationships one banishment at a time.
In episode four, Jessie didn’t hesitate to try and save Jack during the challenge. No explanation was given, and the move felt rather random to viewers.
After the task, Jessie leapt onto Jack in celebration, suggesting a level of intimacy we hadn’t previously seen between the pair. This immediately sparked speculation that they might be brother and sister — especially given that Jack is reportedly engaged.
Adding fuel to the fire, Jack later said he “couldn’t be more proud” of Jessie, a surprisingly personal comment considering the pair supposedly only met when they entered the castle.
For many fans, it was yet another moment that felt like more than a coincidence.
Jack might need to rein in the physical affection, because fans are officially on high alert. One eagle-eyed viewer shared an Instagram video of Jack placing his hand on Stephen’s shoulder almost instinctively as the group huddled together — a small moment that sent the internet spiralling.
Some fans were immediately convinced the pair could be a couple. However, others were quick to shut that theory down after spotting Stephen’s alleged partner elsewhere, suggesting the interaction may point to a close friendship rather than romance.
Some viewers suspect that Harriet and Hugo are either siblings or at least know each other from their work as barristers. Others argue that the theory doesn’t hold, pointing to how Harriet orchestrated his vote-out — though anyone with siblings would know that doesn’t automatically rule it out.
Their debate also felt eerily familiar, as if they were slipping into patterns only people who know each other well would fall into.
Adding to the intrigue is the Latin quote hanging above the family tree in the castle:
“Beware whom you trust as your own blood. The sharpest knives are often handed to the table by faithful servants. Among intimate friends lurk the most secret enemies; take care not to let your confidence become the cause of your downfall and agitation.”
Many viewers are convinced they might be mother and son, pointing to a striking resemblance between the pair. Reece’s instinctive attempt to help Amanda during the skull challenge only added fuel to the speculation, leaving fans wondering just how deep their connection really runs.
We have a sneaking suspicion that Fiona might actually be Reece’s grandmother. Hear us out: he barely flinched when she didn’t save him during the challenge, and he didn’t complain in his confessional — or at least it wasn’t shared, possibly because he referenced their connection. Meanwhile, Fiona seemed unusually relaxed throughout the process, which could make sense if she’s quietly planning to protect her beloved grandson.
Two Northern Irish players, and no, they’re definitely not dating — Rachel is married with three kids, and Matthew is openly gay. But could they be siblings? They claim to hail from different parts of Northern Ireland, though we’ve seen contestants bend the truth about their backgrounds before.
After Claudia selected her Traitors, Rachel and Matthew shared relief that they were both Faithful — though we now know Rachel was bluffing.
What’s particularly intriguing is Matthew telling Rachel how pleased he was she wasn’t a Traitor. Innocent? Maybe. But coming from someone you’d only met an hour earlier, it felt… a little too personal.
These two are clearly close — friends, if not something more. Matthew lives in Edinburgh, while Stephen claims London as his base, though he’s Scottish through and through.
Matthew revealed that if he won, he’d spend the prize money on a home in the Highlands, where he spends much of his time. He also founded a hiking club for queer people, weegayhikeclub, and spends many weekends exploring the outdoors with friends. Stephen, a Highland native, shares that love for all things outdoors — so it’s safe to say these two have plenty in common.
It won’t just be family and romances stirring the pot — we suspect a few colleagues are in the mix too. Take Amanda, a detective, and Maz, a former police officer. Both have kept their professions fairly under wraps, perhaps to avoid appearing threatening… or maybe to prevent their connection from being uncovered.
Hear us out: sure, their accents are totally different — but they look so similar, and we’re not the only ones noticing.
On a Reddit fan forum, one user speculated: “I think Rachel and James are siblings; they have the same chin, big eyes, and beaked nose.”
Another added: “Put a wig on James and he’s basically Rachel.”
Could one of them be faking an accent? Stranger things have happened — Charlotte duped her co-stars with her Welsh voice just last year.
What's next for our Traitors?

Who knows who on The Traitors?
Now, let’s dive into the confirmed relationships on season four of The Traitors. We’ll keep this updated as the secrets unravel.
Early on, we discovered that a mother-daughter duo was in the mix: Judy and Roxy. While Judy stayed composed, Roxy seemed far more concerned with protecting her mum — even almost slipping up and calling her “mum” on one occasion.
Unfortunately, Judy was banished by the Traitors before anyone uncovered their secret.
On Instagram, a holiday post from November showed Ross posing outside his hotel, geo-tagged as Tivoli La Caleta Tenerife Resort. Just weeks earlier, Ellie shared her own holiday round-up from the same resort. While she didn’t tag the location, eagle-eyed fans pieced it together from her poolside photos.
Then a social media sleuth unearthed an old Instagram post from Ross’ work showing them together — a little aha moment for viewers.
But the true confirmation came when Ross was banished: Ellie privately admitted to viewers that he was, in fact, her boyfriend. Don’t worry, she’s planning a little revenge.
This one’s a bit trickier. The pair seemed genuinely surprised to see each other on the show. Netty immediately acknowledged Ross, while he later admitted he had recognised her but chose to ignore her.
Did they know the other would be there before filming? It seems unlikely. Both have already been banished, and neither used the chance to reveal their connection to viewers — unlike other relationships we’ve seen exposed. Coincidence… or a little scheming from the producers?
Let's see which other The Traitors connections get revealed.
Even the most beloved reality show on television holds a mirror up to our unconscious biases.
